[0034] The technical solution of the utility model is further explained below with reference to the accompanying drawings and through specific implementation methods.

[0035] like Figure 1 and Figure 6 As shown, an embodiment of the utility model provides a high pole lamp which can be raised and lowered and adjusted, including a base 1, a lamp pole 2, a lamp holder 3 and a lifting and sliding device 4, wherein the lamp pole 2 is arranged on the base 1, and the lifting and sliding device 4 is arranged on the lamp pole 2, and the lifting and sliding device 4 can move along the height direction of the lamp pole 2, and the lamp holder 3 is connected to the lifting and sliding device 4, and the lamp holder 3 is provided with a plurality of lighting lamps 5 along the circumferential direction; by providing the lifting and sliding device 4, the lamp holder 3 can move along the height direction of the lamp pole 2, so as to adjust the height of the lighting lamp 5 according to actual conditions, so as to adapt to different lighting needs or environmental requirements; arranging the lighting lamps 5 along the circumferential direction can enable the lighting lamps 5 to provide all-round lighting, cover a wider area, and improve the uniformity of the lighting effect.

[0036] like Figures 2 to 4 As shown, the lifting and sliding device 4 includes a circular cage 41, a crawler assembly 42, a connecting rod arm 43 and a clamping drive assembly 44. The circular cage 41 is arranged around the lamp pole 2, and the lamp holder 3 is connected to the circular cage 41. Three groups of crawler assemblies 42 are arranged at equal angles along the inner side of the circular cage 41. The circular cage 41 is movably connected to the crawler assembly 42 through the connecting rod arm 43, and the crawler assembly 42 is in contact with the wall surface of the lamp pole 2. When the crawler assembly 42 moves, it can drive the lamp holder 3 to move along the lamp pole 2. By setting three groups of crawler assemblies 42, the lifting and sliding device 4 can maintain balance and stability during the lifting process, reduce shaking and swaying, and ensure the safety and stability of the high pole lamp.

[0037] like Figure 2 and Figure 3 As shown, the clamping drive assembly 44 is arranged on the circular cage frame 41, and the clamping drive assembly 44 is connected to the bottom of the crawler track assembly 42.

Such a setting can ensure that there is sufficient friction between the crawler track assembly 42 and the lamp pole 2, ensuring that the lifting and sliding device 4 maintains stability during the lifting and adjustment process to avoid sliding.

[0038] like Figure 2 and Figure 3As shown, the clamping drive assembly 44 includes an electric push rod 441, a slide seat 442 and an elastic connecting arm 443.

When the friction between the crawler track assembly 42 and the lamp pole 2 is adjusted to a set value, the driving motor 422 can drive the driving gear 423 to rotate, so as to drive the rubber crawler 425 to move along the lamp pole 2, thereby realizing lifting and lowering adjustment; the setting of the crawler wheel assembly 426 can maintain the stability of the rubber crawler 425, prevent it from shaking during movement, and improve the stability of the lifting and lowering operation.

[0040] like Figure 3 and Figure 4 As shown, further, the outer surface of the rubber track 425 is provided with a convex strip structure 4252 for increasing friction. Such a configuration can reduce sliding or slipping caused by wetness or other factors, and has high safety.

[0041] Furthermore, the circular cage 41 is a detachable structure, and the detachable circular cage 41 structure makes daily maintenance and disassembly and assembly more convenient.

[0042] like Figure 1 and Figure 2 As shown, further, the circular cage 41 includes a first arc frame 411, a second arc frame 412, an arc connecting seat 413 and a locking nut 414; the first arc frame 411 and the second arc frame 412 are connected via the arc connecting seat 413, the first arc frame 411 and the second arc frame 412 can be rotated relative to the arc connecting seat 413 respectively, so that the circular cage 41 is in an expanded or closed state, the first arc frame 411 is provided with a locking screw 415 at one end away from the arc connecting seat 413, the second arc frame 412 is provided with a sleeve 416 at one end away from the arc connecting seat 413, the locking screw 415 is penetrated by the sleeve 416, and the locking nut 414 is used to lock the sleeve 416 with the locking screw 415. When the circular cage 41 needs to be disassembled, the user only needs to rotate and twist the locking nut 414 off the locking screw 415, and then unfold the first arc frame 411 and the second arc frame 412 outward relative to each other, which is convenient for disassembly and assembly.

[0043] like Figure 3 and Figure 5 As shown, further, the elastic connecting arm 443 includes a first connecting arm 4431, a movable rod 4432, a spring 4433 and a second connecting arm 4434; the first connecting arm 4431 is movably hinged to the sliding seat 442, one end of the movable rod 4432 is arranged on the first connecting arm 4431, the second connecting arm 4434 is movably hinged to the side wall of the shell 421, and the second connecting arm 4434 is provided with a guide hole 4435 for the other end part of the movable rod 4432 to extend into, the spring 4433 is sleeved on the movable rod 4432, and the spring 4433 is used to apply elastic force to the second connecting arm 4434. When the electric push rod 441 is pushed upward, a thrust that overcomes the elastic force can be applied to the elastic connecting arm 443 to push the movable rod 4432 to move toward the inside of the guide hole 4435, thereby changing the relative position between the elastic connecting arm 443 and the crawler track assembly 42, thereby achieving the effect of adjusting the clamping force; the setting of the spring 4433 can play a shock-absorbing role, making the crawler track assembly 42 more stable during crawling movement.

[0044] like Figure 5As shown, further, the side wall of the second connecting arm 4434 is provided with a limiting groove 4436 connected to the guide hole 4435, and the side wall of the movable rod 4432 close to the second connecting arm 4434 is provided with a limiting rod 4437 vertically arranged therewith, and the limiting rod 4437 is located in the limiting groove 4436 to limit the moving stroke of the movable rod 4432 in the guide hole 4435. With such a configuration, the clamping force adjustment range of the elastic connecting arm 443 can be controlled to avoid excessive extension or compression.

[0045] like Figure 1 As shown, further, a top seat 21 is provided on the top of the lamp pole 2, and the diameter of the top seat 21 is larger than the diameter of the lamp pole 2.
